In enzymology a RNA uridylyltransferase (EC 2.7.7.52) is an enzyme that catalyzes the chemical reactionUTP + RNAn diphosphate + RNAn+1Thus the two substrates of this enzyme are UTP and RNAn whereas its two products are diphosphate and RNAn+1.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is UTP:RNA uridylyltransferase.
